Mitel is still having issues with AMC licensing.
We had an issue with our Teleworker MBG in July, related to the AMC load balancing. Mitel says all is well, we move on.
Same problem happened with our SIP MBG over the weekend. After two days of troubleshooting, Mitel reports it's a load balancing issue again. So frustrating to have a server (and SIP trunks) off line for three days, with Mitel scratching their heads and suggesting software upgrades.
Just a heads up that the problem still exists.
